The UK government is due to challenge the decision to let Snoop Dogg enter the country at a hearing taking place today.
Snoop was banned from the UK in 2006 after he was arrested at Heathrow Airport on charges of violent disorder in an incident that injured seven officers.
Looks like Heathrow brings out the worst in celebrities.
Snoop was then forced to cancel a tour of the UK with P Diddy in March 2007 after authorities denied him a visa.
The rapper successfully appealed against the ban in January at an asylum immigration tribunal, but a spokesman for the UK Border Agency said they were "disappointed" with the judge's decision.
